Simple application development and deployment for K8s

The purpose of this "training" is to give you an overview of the application development workflow for Kubernetes. During this session, you will:

• Create a simple REST API server application with Python
• In a docker container
• Test it locally
• Push it into a container registry
• Deploy it into a kubernetes cluster (mine running on GCP)
• Expose it to the world
• Scale it up / down manually
• Roll out upgrades

Future things I willing to add to this training:

• Building a CI/CD pipeline for your software
• Setup auto scaling

Pre-requirements

• You understand python code
• You familiar with REST API-s in general
• You able to install the next tools:
  • docker
  • kubectl
  • python
• I made the training on Linux / Fedora, but nothing keeps you from repeat the whole process on Mac or Windows - if you do soo, feel free to add the steps and make a pull request ;)
